Detection of spam/telemarketing phone campaigns with impersonated caller identities in converged networks - A method of detecting a campaign of unwanted telephone calls in a converged telephone network, including populating a first set of caller identifications where no call has been initiated to the caller identification during a predetermined period of time, populating a second set of caller identifications where a call has been initiated to the caller identification during the predetermined period of time, performing a homogeneity statistical test analysis of the first set and the second set, and interpreting the statistical analysis results in order to detect the campaign of unwanted telephone calls in the converged telephone network. Some embodiments include analyzing log messages to determine a source of the most telephone call traffic, and blocking the completion of telephone calls subsequently initiated by the determined source of the most telephone call traffic.

SOFT DENIAL OF APPLICATION ACTIONS OVER THE NETWORK COMMUNICATIONS - A soft-denial system for client-server networks is disclosed for translating server authorization denials into responses that are known to be innocuous to the client application. The soft-denial system includes a client-application which originates a service request across a network to a server-application which rejects the request due to lack of authorization and subsequently provides a denial response. A soft-denial application intercepts the denial response, translates the response into a response known to be innocuous to the client-application, and forwards the innocuous response to the client-application. The soft-denial system is particularly useful for overcoming client-application failures due to authorization expectation mismatches.

MANAGING UNDESIRABLE CONTENT IN IP VIDEO BROADCAST TRAFFIC - A method and apparatus are provided for suppressing display of advertisements within a video over IP stream provided by a content provider. Metadata is prepended to advertisements within the stream. When the stream is received by an access aggregation point, the access aggregation point compares the metadata of an advertisement with preset criteria provided by an enterprise subscriber, and suppresses the advertisement if a comparison of the metadata and the preset criteria indicate that the advertisement is undesirable to the enterprise subscriber. The access aggregation point suppresses the advertisement by switching to a second video channel within the stream for the duration of the advertisement. In this way, the access aggregation point can control display of content provider advertisements without manipulating data within the stream, so as to allow the enterprise subscriber to prevent display of undesirable advertisements to endpoints within the enterprise subscriber site such as set-top boxes within hotel rooms.
